TECHNICAL FIELD

The present invention relates to a henhouse, and more particularly, to a premixed ventilated henhouse.

BACKGROUND

At present, a henhouse is mostly ventilated in a manner of negative pressure ventilation. One gable is provided with a fan thereon, two sidewalls are provided with wet curtains thereon, and fan operates to cause a negative pressure inside the henhouse, so that wind enters through the wet curtains. However, the wind entering the henhouse is relatively strong, especially in seasons of autumn and winter, with a large volume of urgent and cold air. The cold air partially sinks quickly, which is unable to be evenly mixed with hot air in the henhouse, rendering fowls uncomfortable. Moreover, a majority of henhouses are provided with a built-in wet curtain, which is embedded in the sidewall of the henhouse. An outer surface of the wet curtain is merely provided with a simple dust screen, so when an outdoor temperature is excessively low, especially in cold winter in the north, the outdoor cold air is apt to enter the henhouse through the wet curtain, resulting in problems such as that the henhouse is hard to be warmed up. Patent Application No. 201320159133.4 and Patent Publication No. 203136769U disclose an aerosol-type ventilated henhouse, in which a vent-pipe ventilated with external environment is provided on the gable and the sidewall of the henhouse, which is able to achieve an effect of evenly mixing the air. But, foul gases sink and accumulate below within the henhouse, so there are still problems such as that foul gases are hard to be exhausted, and ammonia excesses the standard. In addition, temperature and humidity of outside air are unable to be adjusted and controlled according to an actual situation of the henhouse, which results in a poor overall ventilation effect on the henhouse, and affects health of the fowls.

The pressure chamber discharges the mixed air into the inner chamber, and at a same time, the foul air inside the henhouse, especially the foul gas that sinks in the lower portion of the henhouse as mobilized by the fan of the sidewall and the fan of the vent pipe, passes through the air outlet slot of the inner wall or the through hole of the floor to be discharged, while the fresh air sinks as a whole, so as to implement overall air renewal inside the henhouse. In addition, the wet curtain on the sidewall of the present invention is able to meet a demand for cooling down the henhouse when the outdoor temperature is relatively high, such as in summer. The thermal insulation curtain is also provided, which plays a role in keeping the henhouse warm when the outdoor temperature is relatively low, such as in winter, and plays a dustproof role on the wet curtain body. In the present invention, the wet curtain body is provided on a fixing plate, and the fixing plate is hermetically embedded on the sidewall of the henhouse, so in summer, when the wet curtain works normally, the henhouse can be normally ventilated and cooled. When winter comes, the henhouse can be thermally insulated according to the actual outdoor temperature. By pulling down the thermal insulation curtains on both sides of the wet curtain body, it is possible to avoid the outdoor cold air from entering the henhouse, so as to achieve an effect of heat preservation.
